PROBLEM TO BE SOLVED: To provide a gas sensor that prevents calking on the outer surface of a bent part from cracking or peeling a plated layer and prevents corrosion of the bent part, regarding a main body metal fitting including a main body part and the plated layer for covering the main body part.SOLUTION: The gas sensor includes a gas detection element 120, a main body metal fitting 160 having a bent part 161, and an outer cylinder 130 having a collar part 131. The collar part 131 of the outer cylinder 130 is disposed inside the main body metal fitting 160 in the radial direction, and is fixed in a state in which it is pressed to the tip side of the axial direction by the bent part 161 of the main body metal fitting 160. The main body metal fitting 160 includes a main body part 160b and a plated layer 160c covering the main body part 160b. The minimum value (minimum curvature radius) of curvature radius R of the outer surface 161f of the bent part 161 is 1.5 mm or more. |
